Yade is an extensible open-source framework for discrete numerical models, focused on the
Discrete Element Method. The computation parts are written in c++ using a flexible object …

Bed permeability is a crucial factor in blast furnace efficiency and stability. The Discrete
Element Method (DEM) has been used extensively to model material flow in different parts of …

A century after the first attempts of Wentworth to characterise the shape of cobbles, our
understanding of particle morphology is still expanding. A plethora of shape indices has …

Establishing a mesoscale model of asphalt concrete is significantly challenging due to its
inherent heterogeneity and high proportion of aggregates. Initially, a novel approach for …

Wadell roundness is a general particle shape descriptor used in many fields, such as mining
engineering, civil engineering, and geotechnical engineering. Initially, Wadell roundness …

Particle shape plays a key role in the mechanical and rheological behaviour of particulate
and granular materials. The simulation of particulate assemblies typically entails the use of …

The round robin test (the simultaneous analysis of the same problem) is a method to
investigate the variance and sensitivity of results provided by different analysts for a given …

This paper investigates the effect of grain form on the mechanical behaviour of a railway
ballast aggregate using large-scale shear box tests. The speciality of the research is that …

Railway ballast deteriorates over time due to cyclic loading and environmental factors,
necessitating its replacement to maintain track stability. However, the potential shortage of …

Particle morphology is a fundamental property of granular geomaterials such as rock and
soil. A reasonable characterization of irregular particle morphology is of great significance …
